If the cross-sectional area of a wire is decreased while all other factors remain the same, how will the resistance change?
A. It will increase
B. It will decrease.
C. It will go to zero.
D. The cross-sectional area does not affect the resistance.

A. It will increase

Explanation:

Area of a wire is:

R = ρL/A

where ρ is the resistivity of the wire,

L is the length of the wire,

and A is the cross-sectional area.

If A decreases, while ρ and L stay the same, then R will increase.

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

less than one you can't create energy
